THE RANCH STYLE HOUSE
Here the power unit is mounted in the
garage. The intake and exhaust
tubing, the only exposed tubing in the
installation, runs up the garage wall and
into the attic. The trunk line runs
horizontally through the attic from the
power unit to the farthest inlet
location. Branch lines spread throughout
the attic, connecting the trunk line to the
inlet tubing. Each inlet tube is threaded
vertically through an inside wall. Located
in hallways and in large rooms, the inlets
are placed to provide maximum access
to all cleaning areas. See Figure 1.
THE TWO-STORY HOUSE
A double-trunk line system is commonly used in two-story
houses. In the installation shown at right, the power unit is
mounted in the basement. The intake tubing runs up the
basement wall and connects to the main trunk line, which
runs along the unfinished basement ceiling. Two first-floor
inlets are connected to the basement trunk line by vertical
inlet lines run through interior walls. In the center of the
house, a vertical branch line runs from the basement trunk
line, through stacked closets, up into the attic. A second
trunk line runs across the attic and two branch lines connect
to inlet lines which are dropped down through upstairs
interior walls. See Figure 2.

The NuTone central cleaning system consists of a power unit, PVC tubing and fittings, wall inlets, a flexible hose and
various cleaning attachments.
The power unit is designed to be wall-mounted away from the living area of the home and connected to the living area by means
of permanently installed in-wall tubing, fittings and inlets.
Generally, an installation will require 3 to 4 inlets and 16 to 20 feet of tubing per inlet. It is suggested that a floor plan be used
to more accurately determine the quantity of materials needed.
Use the following examples as an aid in planning the installation in either new or existing construction. You should be able to
adapt the examples shown to your specific home layout.
FIGURE 1
FIGURE 2
SYSTEM PLANNING AND LAYOUT
THE SPLIT-LEVEL HOUSE
Like the two-story house, the split
level installation commonly calls for a
two-level trunk line. Here, the power
unit is located in the garage. The
intake tubing runs exposed up the
garage wall and into the ground level
section's attic. Two branch lines
connect this part of the trunk line to
inlet lines which are dropped inside
interior walls. A vertical branch line
runs to the upstairs attic, where the
trunk line branches into a T-shape.
This trunk line connects to two
upstairs inlet lines and to one inlet line
which drops through an upstairs wall
and down into the third-level utility
room to service this entire level. See
Figure 3.

LOCATING THE POWER UNIT
Locate the power unit at the lowest possible position
away from the general living area in an accessible
location for changing the filter bag or debris bucket.
When planning, remember the power unit is equipped
with an inlet to service a garage, basement, utility room,
etc., wherever it is located.
Locate the power unit within six feet of a grounded
electrical outlet. The VX475 and VX550 power units
require a 120 V, dedicated 20-amp branch circuit with a
NEMA 5-20R receptacle. The VX1000 power unit
requires a 240 VAC, dedicated 20-amp branch circuit
with a NEMA 6-20R receptacle.
Do not locate the power unit close to a source of extreme
heat (i.e., water heater) or in an area with a high ambient
temperature (i.e., attic, furnace room).
If the power unit is located in a closet or a small utility
room, make sure the area is well-ventilated (i.e., with
door louvers).
Exhausting the power unit to the outside is recommended
for optimal performance. The exhaust should not be vented
into a wall, a ceiling or a concealed space in the house.
The exhaust line should be vented outside the home
using a Model 393 or CI330 wall caps.
TUBING AND WALL
INLET LOCATIONS
1. Locate inlets on interior walls, choosing central
locations which allow several rooms to be cleaned from
a single inlet using a 30-foot long hose.
2. The tubing installation should consist of a main trunk line
running from the farthest wall inlet to the power unit
location, with branch lines running to each additional
inlet. Keep all tubing lines as straight as possible and use
as few fittings as possible.
3. Beginning at the area farthest from the power unit,
choose a tentative inlet location. Measure 30 feet from
the proposed inlet location to the farthest corner of the
rooms to be cleaned by that inlet to determine if inlet
location is proper. If working from blueprints (or building
plans drawn at 1⁄4" = 1 ft. scale), use a 7½" chain as your
guide to determine inlet locations.
4. Locate inlets within six feet of an electrical receptacle
to allow use of optional current-carrying hose.
5. Be sure inlets will not be blocked by doors or furniture.
6. Be sure inlets will not interfere with electrical, plumbing
or other mechanical installations.
7. Move tentative inlet location if necessary. Use the same
procedure to determine each additional inlet location,
always working toward the power unit.

WORKING WITH
PLASTIC TUBING
Cutting the Tubing
Before you cut a length of tube, accurately measure the
length you need. Allow 5/8” of tubing for inserting into
fittings and 1 ½” for placing into flexible tubing. Cut the
plastic tubing with a hacksaw, making sure that the cut is
exactly square. (You can use a tube cutter if one is
available.) Use wire cutters or tin snips to cut flexible
tubing. The 8” lengths of flexible tubing supplied with each
inlet should not be cut. See Figure 4.
Use a small knife to remove any burrs from the inside of the
tube. You can also use steel wool to remove burrs. The burrs
must be removed or they may impede air flow of form clogs
by snagging hair and carpet thread. See Figure 5.
Next, use a file to slightly bevel the outside of the tube so
that it will easily slide into the fitting. Use steel wool or a light
grained sandpaper to buff the surface of the tube which will
be glued. This will clean the tube and assure a good seal.
See Figure 6.

Making a Joint
Insert the tube into the fitting, aligning the two parts as they
will be installed. Mark the tube and the fitting so that you can
quickly realign the joint. See Figure 7.
Apply cement only to the outside of the tube. Dab the
cement generously in an inch-wide band. Insert the tube into
the fitting with the alignment marks a quarter turn apart, and
then quickly push and turn the fitting to align the marks and
spread the cement. Allow one minute for the joint to dry. You
may also use electrical tape or duct tape to further seal the
joint. See Figure 8.
Cementing Flexible Tubing
Make sure the ends of the flexible tubing are even—trim if
necessary. When you join flexible tubing to plastic tubing or
to an inlet mounting plate, apply cement to both the inside of
the flexible tubing and the outside of the plastic tubing or
mounting plate tubing ring. Twist the two pieces as you join
them to evenly spread the glue. Allow five minutes for the
cement to set in flexible tubing. You may also use electrical
tape or duct tape to further seal the joint.
Secure Wire to Tubing
The low-voltage power wiring is run along with the tubing. To
insure that the wire is secure and will not hang-up in a wall,
use electrical tape to attach the wire to the tubing. Tape the
wire approximately every 12-18 inches. See Figure 9.

INSTALLING THE TUBING
Use the following installation guidelines when installing tubing.
1. Start tubing installation at farthest inlet and work toward
the power unit.
2. Tubing run to the power unit should be as straight as
possible.
3. When assembling sections with elbows and tees, make
sure the curve in the fitting is aligned so that the air flows
toward the power unit.
4. Branch lines should always join the trunk line from above
or from the same level. Never join a branch line from an
angle below the trunk line.
5. Refer to Figure 25 on page 9. Run low voltage wiring
(Model 376UL) and secure wiring to tubing as tubing is
installed. Model CF380 Pipe Support can be used to
support long runs of tubing (position near joists) and to
clip wire along tubing. Secure tubing to joists or studs.
Leave approximately 6" of wire for connection to each
inlet.
6. Cut a 2 ½" diameter hole in sole plate, header or stud
directly in line with opening of inlet bracket fitting.
NOTE: See Figure 13 for center line dimensions.
7. Refer to Figure 14. Measure length of tubing needed to
connect inlet to trunk line. Allow approximately 3⁄4" of
tubing for inserting into fittings.
8. Refer to Figure 15. Cut tubing, keeping cut square.
9. Refer to Figure 16. Remove burrs from both inside and
outside of tubing.
10.Before cementing, pre-assemble section to inlet
fitting, check for proper length.
11.Refer to Figure 17. Apply PVC cement (Model 379) to
outside of tubing. Coat tubing approximately 1" back.
Take care to keep cement from inside of tube.
12.Refer to Figure 18. Insert tubing into fitting with a twisting
motion to evenly spread cement. Be sure tubing is firmly
seated in fitting.
13.If fittings have been attached to tubing at the end opposite
the inlet bracket, be sure alignment is proper before
cement sets.
14.Refer to Figure 19. Tape wire to tubing to hold in place
and insert through hole in inlet bracket.
15.Connect each inlet line and branch line into main trunk
line. Complete low voltage wiring as main trunk line is
continued back to power unit.

WALL INLET INSTALLATION
Model CI370 Wall Inlet (CF361 and CF361F
Rough-In)
1. Remove the cardboard plaster guard.
2. Refer to Figure 20. For some drywall or panel
construction, the plaster frame will extend beyond the
finished wall. In this case, remove plaster frame from
mounting bracket by removing mounting screws.
NOTE: When using the model CF361 and CF361F inlet
bracket on walls thinner than 1⁄2", use a 1⁄4" spacer (not
furnished) between the wall and the inlet bracket. See
Figure 23. Spacer may be made from plywood, Masonite™,
etc. Contact cement may be used to hold spacer in place
during assembly. Configuration of spacer may vary depending
upon installation.
3. Refer to Figure 21. Connect the red striped wire of the
2-conductor low voltage cable to the unused terminal
screw on the inlet. Connect the remaining wire to the
black pigtail wire. Cap off both wires using wire nut
(supplied).
NOTE: The LED indicator light used in the CI370 is polarity
sensitive. If the 2-conductor cable used to connect the inlet
to the power unit does not have a polarity marking and the
CI370 is wired backwards, no damage will result;
however, the indicator will light RED instead of GREEN
when the hose is inserted into the inlet. To correct this
condition, simply reverse the 2-conductor connections at the
CI370 inlet.
4. Guide excess wire back through the hole in inlet bracket
and flanged fitting.
5. Refer to Figure 26. Place inlet into mounting bracket and
secure.
NOTE: When wall inlets are installed in walls that are less
than 1⁄2" thick or when inlets are installed back-to-back in a
wall, the tube of the wall inlet may extend into elbow area of
the flanged fitting and cause blockage. Shorten the wall inlet
tube to prevent this condition. Refer to Figure 24.
For extra thick walls, use Model 399 Extension Sleeve to
connect inlet to the flanged fitting.

(CI395RK ROUGH-IN)
1. See Figure 27. Fasten the mounting plate to a stud
within three studs (48") of an electrical outlet box.
Measure and mark the wire 10" from the plug (A). Feed
the wire through the top hole in the mounting plate (just
above the circular opening). Snap the molded plug into
the mounting plate as pictured (B). This will keep it secure
and out of harm’s way during drywalling and finishing.
Line up the wire at the previously measured 10" mark with
the strain of relief channel on the back of the mounting
plate. Secure it in place with the supplied wire tie (C).
2. Run the inlet wire to the adjacent electric box. If you must
run wire through a stud, drill directly through the center
of the stud (D).
3. See Figure 28. Place the exposed ends of the two wires
into the electrical box through a strain relief channel (E).
Tighten the strain relief channel (do not overtighten) on
the white sheathing leaving 1⁄2" of this sheathing
exposed inside of the outlet box.
Fold the 6" of black and white wire into the outlet box. Leave
the wires to be connected by the electrician when plug
receptacles are being installed. (Attention: Power tools such
as routers are not recommended for use with the inlet
installation, as removal of drywall with these devices may
cause damage to the mounting plate and/or inlet plug).
4. Once drywall and finishing processes have been
completed, remove molded plug from mounting plate
(with the aid of a slot screwdriver) and snap it into the
wing slot at the back of the inlet (F). (NOTE: molded plug
fits one way only, with the narrow opening at the top).
Insert inlet into the mounting plate and secure inlet to
mounting plate with screws provided.
NOTE: All electrical devices such as the electrified inlet
should be reported to the construction electrician for
listing on the inspection report for building inspection
purposes.
NOTE: Plumb inlet to tubing using NuTone Model CF382S

LOCATING ACCESS KEYS IN
EXISTING CONSTRUCTION
Unless your home is a ranch-style house where a single
trunk line can run directly through the attic or basement, you
should first investigate your house to find the key
to running your tubing from level to level. Look
for an accessible area free from obstructions that will
accommodate the 2" tubing.
If you understand how your existing home is constructed, it
can be relatively easy to find access routes to run the
tubing. Refer again to the illustrations on pages 3-4 as you
consider your home construction.
Some of the keys you might find in your home are illustrated here.
Stacked Closets or Laundry Chute
Many homes will have an upstairs closet located directly
above a downstairs closet. It is easy to run the tubing from
one floor level to another inside these stacked closets. In
these installations the tubing is often left exposed inside the
closets. See Figure 30. A laundry chute could also provide
access from basement to upper floors. You may also want to
consider running exposed tubing through cabinets or
cupboards.
Cold-Air Return
A cold-air return often provides a straight run from basement
to other levels of the house. See Figure 31. The ductwork is
easily cut for access. Seal around the tube when completing
the installation.
Use the following procedures for installation in existing
construction. Wall inlets in existing construction may be
accessed from below (basement or crawl space) or from
above (attic). Instructions apply to either method.
Starting from farthest wall inlet location, install each inlet as
described below. Working back toward power unit, connect
each inlet line and branch line into main trunk line. See page
26. Complete low voltage wiring as main trunk line is
continued back to power unit. Mount power unit and
complete wiring. See pages 31-33.
AVOIDING IN-WALL OBSTACLES
The tubing which connects the inlet into the trunk line is
threaded through interior partition walls. After you’ve
chosen an inlet location, make sure the wall doesn’t
contain some hidden obstacle which will prevent you from
running tubing to the inlet.
Exterior Walls
. The insulation in these walls will
prevent you from running tubing through them.
Electrical Wiring
. Wiring may not obstruct your
tubing, but you should always make sure that tubing does
not damage the wiring. Electrical outlets and wall
switches are signs of wiring.
Ductwork
. Avoid choosing a section of wall that
contains ducting. If you see signs of ductwork—such as floor
or ceiling registers—move your inlet location to another
section of the wall.
Plumbing
. Plumbing may or may not prevent you from
running tubing through a wall. If you must choose a
plumbing wall for an inlet location, be extremely careful
when making a cutout in the wall.
Wall Studs
. Make sure your location is between wall
studs. Locate studs by tapping walls, looking for
electrical outlet (usually fastened to studs), or noticing
finishing nails in the floor molding.

INSTALLING THE INLET TUBING
When your planning is complete, you will have to determine
where all the inlets and the power unit will be located. You
have also mapped out the location of your trunk line and
found the access you need to run vertical tubing from one
level of your house to another level. You should have
acquainted yourself with the methods of joining plastic
tubing and acquired the tools you’ll need to install your
NuTone Central Vacuum System. Now, you can begin installation.
The first step to install the inlet tubing which connects the
wall inlets to the branch lines. As explained before, the inlet
lines run inside interior walls. You will find access to these
walls through your attic or basement. Briefly, you want to find
the exact location in the wall, drill an access hole through the
wall plate or header, and insert the tubing into the wall cavity.
This part of your installation requires close observation and
careful measurements. Take your time and make sure you
accurately line up your access holes with the locations
you’ve chosen for your wall inlets.
Locating Attic Access Holes
Drill the access holes directly above the inlet location.
To accurately locate the access hole, you must find the
space between wall studs where the inlet is to be located.
Observe the area around the inlet location. Look for
references you might be able to find in the attic: electrical
wiring, ductwork, doorways, etc. Measure and note the
distance from these references to the inlet location.
Enter the attic and find the inlet wall. Have a helper
downstairs knock on the top of the wall right above the inlet
location; locate the general area by following the sound.
Most likely, you will have to clear away insulation. Ask your
helper to continue knocking until you locate the area
between wall studs directly above the inlet location.
Next, measure the thickness of the wall. Mark the exact
center of the wall where you will drill the access hole.
Remember that the access hole must be placed exactly in
the center of the wall.
Locating Basement Access Holes
To locate access holes in the basement, remove the toe
molding or baseboard at the base of the inlet wall. Carefully
loosen the molding or baseboard by inserting the blade of a
putty knife behind it. Force another putty knife between the
first knife and the baseboard or wall. Gently hammer a cold
chisel between the two knife blades, prying the loosened
molding away from the baseboard or the baseboard away
from the wall.
Directly below the inlet location, drill a 1/16” reference hole
through the floor into the basement. (If you’re drilling through
carpet, use an awl to slightly open the weave. This will keep
the carpet from wrapping itself around the drill bit.) Insert a
piece of scrap wire or a clothes hanger into the reference
hole so you can easily find the hole in the basement.
Once you’ve found the location in the partition wall, you
must center the access hole in the middle of the wall.
Measure half the thickness of the wall and mark the
center of the wall where you will drill the access hole. If you
cannot see the plate, you can determine this measurement
from upstairs. At the nearest doorway, measure the
thickness of the wall, including the baseboard.
In the basement measure a distance equal to half the
thickness of the wall, using the reference hole as a starting point.

Drilling the Access Holes
Once you are certain that you’ve located the center of the
wall directly above the inlet location, use a 2½” hole saw to
cut the access hole through the wall plate or header and into
the wall cavity. (A 1/2” drill is recommended.) Carefully
remove the drill from the hole.
Now, use a flashlight to inspect the wall cavity through the
access hole. Make sure no hidden obstacles will interfere
with the tube installation. (If this inspection reveals an
obstacle, find a new inlet location.) Repeat this procedure in
your attic or basement until your access holes are drilled.
Assembling the Inlet Tubing
Once you’ve drilled the access holes, you assemble the inlet
tubing and insert it into the wall cavity. Refer to “Working
With Plastic Tubing” on pages 5-6 before you begin to
assemble the inlet lines.
Select a section of plastic tubing and an 8” section of the
flexible inlet tubing. Apply cement to the outside of the
plastic tubing and to the inside of the flexible tubing. Join the
two pieces together and allow 5 minutes for them to dry.
Cut a piece of low voltage wire which is long enough for the
complete inlet line, allowing 6” for connections to the inlet
wall plate. Secure the wire to the tubing with electrical tape.
Tuck the 6” wire lead
inside the flexible tubing
so that it will not snag
inside the wall.
If space permits, you can
assemble the entire inlet
line by joining two
sections of tubing with a
stop coupling before
dropping the assembly
into the access hole.
(Remember to only glue the outside of the tubing when join-
ing two pieces of PVC tubing.) Oftentimes, tight attic spaces
require you to begin your drop and then join the second sec-
tion of tubing. Of course, the order of assembly, and the
length of tubing required depend on your attic space and
your wall height.
14
AO0014
Whatever the case, insert the completed inlet line into the
access hole and thread it down inside the wall. The inlet line
should be long enough so that it extends above the joists in
the attic; at this height, it can be easily connected to the
branch and truck lines. When cutting the inlet tubing to
length, remember that your inlet will be placed at 18” above
the floor.
For a basement installation, assemble the tubing to the inlet
flexible tubing in the same way and insert it into the access
hole. A basement inlet line is necessarily shorter because it
must only reach 18” from the floor to the inlet. Most of the
time, Basement inlet lines are more easily installed by two
people after the inlet
hole has been cut in
the interior wall. See
“Wall Inlet Installation.
Complete all your
inlet lines, and then
proceed to your inlet
installations.
WALL INLET INSTALLATION
The wall inlet design allows you to work outside the wall
—where assembly is easy and all the parts you need are
accessible. First, you make a cutout into the wall and locate
the flexible tubing attached to the inlet line which you
previously threaded into the wall. Then, you attach the flexible
tubing to the inlet mounting plate, assemble the other inlet
parts, and make the wiring connections. You place the inlet
assembly into the wall cutout, sandwiching the wall between
the inner and outer parts, and secure the inlet tightly to the
wall with two screws.
Assemble and install the wall inlet as shown in the
illustrations and as explained in the next few pages.
Be careful and patient as you make your first cutout and
install your first inlet by following the procedure step by step
—the other inlets will be easy to install in very little time.
Making the Wall Inlet Cutout
The wall inlet should be
located 18” on-center
from the floor and
directly in line with the
attic or basement inlet
tubing hole you have
already drilled in the wall
plate or header. the wall
inlet cutout must be
exactly 3
7
8” high by 2
7
8
wide. It is crucial that you
make an accurate
cutout, and we have
supplied a template to
help you.
Place the template against the wall so that it is 18”
on-center from the floor. Use a level along the top edge of
the template to make sure it is square to the wall. Mark your
wall for the cutout by
tracing around the
inside of the template.
Then use your pencil
to mark the screw
hole locations through
punched holes at the
top and bottom of the
template. Remove the
template from the wall.
15
Use an awl or icepick to punch pilot holes where you marked
the two hole locations. Now, drill two 3⁄8” diameter holes,
using the pilot holes as the centers. Locate and drill these
holes exactly as marked with the template.
Also drill four pilot holes in the four corners of the marked
area. Make sure these holes are located inside the marked
line. Then, using a utility knife, score along the inside of the
marked line. For plaster walls, score the plaster deeply,
being careful to stay inside the marked line.
Next, use a keyhole
saw or a sabersaw to
make the cutout.
Again, be extremely
careful to cut along the
inside of the marked
line.
Attaching the Inlet Mounting Plate
Reach through the inlet hole and locate the inlet tubing.
Raise it up inside the wall until you locate the inlet tubing. If
the inlet is connected from the basement, have a helper
insert the inlet tubing into the access hole until you can see
the flexible tubing. Then, pull the flexible tubing through the
inlet hole and remove the low voltage wiring from inside the
tube. If the end of the flexible tubing is not even, trim it so
that it is exactly even.
Now, remove the nail flange (used for new construction)
from the inlet mounting plate. Use pliers to bend this flange
along the scored lines until you can break it off.
Apply cement to both the
inside of the flexible tubing
and to the outside of the
mounting plate’s tube ring.
Insert the mounting plate’s
tube ring in the flexible tubing
and twisting the pieces as
you join them to spread the
cement, and align the mounting
plate in a vertical position.

CAUTION
When cutting into
plaster walls, make
sure the plaster is
firm and secure
around the cutout
area.
Hold the assembly in place
for a few minutes as the
cement sets; allow 5 minutes
for the cement to completely dry.
Now, strip the ends of the two
low voltage wires, and then
connect the wires to the
screw terminals on the back
of the inlet cover. Make sure
the wires are tightly secured
under the terminal screws. When the wiring is complete,
assemble the inlet cover to the tube guard and mounting
plate. Insert the top screw through the entire inlet assembly
until the screw engages the mounting plate.
Completing Inlet Assembly
Once you have attached the mounting plate to the flexible
tubing, pull the low voltage wire through the top wiring hole
in the mounting plate.
Installing the Inlet
When you place the inlet into the wall cutout, the mounting
plate and tube guard slip inside the wall; the inlet cover
remains on the outside.
Holding the inlet assembly
between your thumbs and
fingers, angle the bottom
of the mounting plate into
the cutout. Push the
assembly downward until
you have clearance at the
top of the cutout.
Push the top of the mount-
ing plate into the cutout
and lift the assembly
upward until the top screw
seats in the predrilled hole.
At this point, the wall should be sandwiched between the
mounting plate and the frame plate.

Insert the bottom screw into

in the mounting plate. Now,
level and slightly lower the
assembly. Make sure the wall
is sandwiched between the
inner and outer parts—you’ll
be able to feel if mounting
plate is firmly centered on the
inside of the wall.
Hold the inlet in place and gradually tighten down each
screw a little bit at a time. (If you completely tighten down
one screw at a time, the mounting plate may pull away from
the wall at the loose end and slip back into the cutout.)
Complete all your wall inlet installations in this manner.
If your cutouts are accurate, each wall inlet will install more
quickly and easily.
